A 26' Claims.

-My invention relates to machines for applying adhesive coatings, moreparticularly to shoe-soles. The embodiment of the invention-illustratedherein is adapted for the temporary attachment of a heel-breast-flap tothe body of a 'sole from which it has been divided. An application forLetters Patent of the United States, disclosing another embodiment ofthe invention and containing claims generic to the present case is filedsimultaneously herewith, it having the'title Coating machine and bearingthe Number 8,003.

It is a common practice in connection with womens shoes to split fromthe grain-side of a Sole a thin flap, which may later be cemented to thebreast of a heel attached to the'shoe, to furnish a covering for saidbreast. Between the splitting and breast-covering operations, variousother manufacturing steps occur involving the sole. For example, in acement-process shoe, there are the operations of shank-reducing,roughing of the flesh-side, the application of cement and then a solventthereto, and the pressing of the sole upon the shoe-bottom; While thisis being done, the rather frail, loose breast.- flap is obviously liableto injury,-as by creasing or tearing. It is an object of my invention toguard against diificulties of this character, and With this in view Ihave provided a machine which may, among its various uses, be employedto temporarily attach a breast-fiap'to ,the opposed surface of its sole,to be separated therefrom when it is to be cemented to the heel-breast.

For the attainment of the above object, I combine, asa feature oftheinvention and in a novel manner, a turning member. in engagement withwhich a sole is advanced to separate the breast fiap therefrom, and acement-applying member into co-operation with which the separatedsurfaces are carried inthe continued advance of the work. Preferably,the application of the adhesive is to a portion onlyof the sole-surface.By successive steps the work is thus prepared for the coating and saidcoating applied. Thereafter, the attaching operation may be completed bythe action of means which brings the separated surfaces together andapplies pressure thereto. The heel-breast-fiapis inthis way held to thebody of the sole, so, it will not be liable to injury, as it would itloose. Yetfwhen] the flap is to be 'cementedto the heel-breastit mayreadily be freed from the sole-body by the operator, who can grasp theuncoated portion and separate the entire flap. Theparticular'instrumentalities .herein illustrated for performing thesuccessive operationsupon the work include a supporting table alongwhich extends acurved flap-turning plate, a pair of rolls receiving thework from the plate and to one of which rolls cement is supplied, and apair "of pressure-rolls situated at one side of' the cementing rolls. Asalready indicated, this combined work-arranging, cementing and pressingmeans and its sub-combinations are not necessarily limited to their use7 for sole-flap-attachment, but may be novel in 5 other connections.

' In operations of this sort, in which separated surfaces are pressedtogether, the work-portions are liable to be displaced laterally withrelation to each other, especially when one, as a flap' divided from asole, is thin. Another feature of my invention guards against suchdisplacement. With coating and pressing means for work-pieces, betweenwhich pressing means and work-pieces there is relative movementlongitudinally of the coated surface, I associate 'm'eans contactingyieldably with the opposite edges of the pieces at the pressing means toprevent their displacement during the relative longitudinal movement.The members furnishing the work-contacting means 20 may be positioned byengagement with oneworkpiece while they are positioning anotherworkpiece. This wo-rk-positioning means may further be controlled byactuating means for the pressure member, asthrough connections to atreadle or other operator-governed member by which the pressure membersare caused to engage the work. In this way, the positioning members maybeheld inactive to receive the coatedwork-pieces while the pressuremembers are separated, and then freed to exert their work-positioningeffect when the pressure members are rendered active.

A particular embodiment of the invention is shown in the accompanyingdrawings, in which Fig. 1 is a front elevation of my improved machine,portions being broken away; Fig. 2, a top plan view taken below theapplying roll;

Fig. 3, a vertical sectional detail of the,,coating rolls andpressure-rolls; and

Fig. 4, a detail in side elevation of said pres.- V sure-rolls,illustrating the last operation upon the work. V V Upon a frame it! iscarried ahorizontal worksupporting table 12. Extending along this table,between the opposite sides, .is a'fiap-turning plate l4. The plate maybe secured to the table by a downward extension [6, which holds'itslower edge so spaced at I8 fromthe work-supporting surface that thebody-portion of therear of a sole S from which a heel-breast-flap f hasbeen divided may be slid beneath it over the table from front to rear ofthe machine. The plate I 4 is curved reversely, first extending upwardlyand rearwardly of the machine at aQthen turn ng at b and curvingforwardly and downwardly at 0. Consequently, if the heel-end of a solewith a breast-flap loose-upon it is inserted beneath the plate, asindicated in dash-dot lines in Fig. 2. a

3 the flap will pass above the plate at its outer to left (Fig. 2), itwill be folded back over the" side and be turned up by it to clear thesole.- body. Then, as the work isadvanced from right body'as'appears inFig.3. The work is thus prepared for the application of an adhesive tothe surface s from which the flap f has been separated.

' ..Beyond the table 12, m the direction in which the work is advancedby the operator, is a cement-applying mechanism M. This may consist of alower work-supporting roll and'an up per applying roll 22, the latterbeing-shown'as provided with pockets in which the cement may be held forapplication to the work. The rolls- }are gearedat 24 to rotate together,in the directions. indicated by the arrows in'Fig. 1, from'a source,.of. power not appearing. The cement m y e supplied to the. app yn oll from. a

receptacle 26 mounted upon the, top of the frame and deliveringrthrough'a valve 28.; The lower roll is shown as held'yieldably up to urge the'workagainstthe applyingroll, which .iS jouri naledhorizontallyinthe'frame, by a spring 30 acting upon a depending arm of a lever 32 inThe bite of therolls 2 0 and 22 is horizontally 'alined with the spaceI8' which said roll turns.

between the tableand plate butis so located transversely with respect tothe lower edge of the plate, that, as the sole leaves said plate andpasses between the rolls, the rear portion of the surface s will; as isillustrated in full lines in Fig. 2, project at 'u beyondthe rolls so itwill re- 7 :--main uncoated, while the remainder of the surflap'and' thesole will receive an application'of faceito a line adjacent to thejuncture of the the adhesive. V

The work'is now ready for the pressing of the flap 1 against the'surface8 upon its further advance, this being; in another direction from thatfor flap-turning and cementing. Situated at one side of the rolls20;:and22 of the applying mechanism, with their axes substantially atright angles totheaxes of the coatingrolls, are hori-' zontal lower and.upper.pressure-rolls 34 and 36, .the bite of the'latterv rollsbeing'preferably somewhat below that of the coating rolls. 7 The lowerroll 34.15 shown as J'ournaled in a standard as rising from the bottom'ofthe frame [0. The

roll '36. turns about a spindle 46 projecting inwardly from an arm .42pivoted upon the frame.

{Both of thesepr'essure-rolls may be idle; Pivcted to' the arm 42 is arod 44 joined to a treadle .46.. A spring 48, interposed between theframe and a collar 50 fast upon the rod,.holds the roll 36 normallyraised. clear of the roll 34 to an extent. determined by the contactwith the frameof a stop-co1lar52 upon the rod. By depression of thetreadle, the roll 36 may be lowered into contact with work with itscoating of cement, which 'isjcarried between the rolls 34, 36 by theoperator fromthe'rolls 20 and 22. To prevent the flap f frompassing .tothe outeror forward side of the. roll 36, and. to. prepareit for beinglaid upon the sole-surface s, the spindle 40 has a head 54." Thisappears as tapering from the diameter of the roll 36 downwardly to asomewhat rounded .end, which overlaps but is spacedoutwardly from theportion dot the plate I4 at a point just above the space 'I8. Therefore,as the solein its advance is about to pass beyond the plate l4 and enterbetween the cementing rolls20 and 22, the flap contacts with theinclinedsurface of the head 54 and is thereby directed above the pressure-roll36. When the'work" has reached the full-line-position of Fig. 2, theoperator maydepress the treadle 46 to lower the roll 36; Then he maydraw the sole outwardly between V the rolls 34 and 36 at right anglesto-the direction of its previous travel. [In this movement, en- 5gagement of the flap with the roll 36 lays said 'flap'down graduallyupon the surface s of the sole, andthe opposite pressure of the'tworollsis sufficient to produce the desired adhesion of Q 'theflap to thesolebody. .lo

As thefiap'may be rather flaccid, a is name to lateral displacement atthe pressure-rolls 34' and 36, soit might not belald properly but. be

creased or otherwise mutilated in its passage between. the rolls. [ThisI avoid in the following 15 manner: Just at the, rear: ot. the;pressure-rolls is located a P ir of flap-positioning members .1 shownas furnished byfarms '60 and'62.. '1hese are pivoted at 64 upon theframe to-swing inde-J pendentlyof each other. They, are yieldably 2 0'=drawn toward each other by a spring 66 connecting them. The normalposition of the pair of arms is under the control oftreadle mechanism; 77

To thisend, to the collarjlupon the treadlerod 44. is pivoted onearm ofa' bell-crankelever 25 10. fulcrumed upon the frame. To the other arm ofthis lever is articulated a link I2 pro vided with a horizontal slot14inwhich lies a projection. 68from the 62.. 'When the 1 treadle .46 and itsrod are in their initialraised 30 relation, the outer end of the slot,by contact with the projection, limits the anticlockwise movement 1 ofthe arm 62 (Fig. 1). Atthe same time-the spring 66 urges the arm 66 in aclockwisedirecj tion', the extent of thisgmovement being deter- 35.mined by engagement of said arm 60 with a pro fl jection 16 fromtheframe. The spring also holds the projection 68 againstJtheslot-end.A' depre s- .sion 18 atthe upper extremity of the arm '60 now. lies in aplane just abovetheroll and not greatly removed from its longitudinalcenter. Theupperend of thecompanion arm, which has alike. de-

pression 18, will be below the top of the roll; r

the operator advances the work, with' its coating of cement, fromtherolls 20 and 22between the 45 rolls 34 and 36, the forward edge offthesole will strike the arm 60 at the depression' 'l8, said arm-- itforward; At this time the treadle is depressed tolowerthe upper roll 36upon the work. Ther end of the slot in the ink 12 is thereb'y carriedawayfrom the. projection, so the spring-66is f allowed to draw the arm62' atthe depression 18 155. against the inner edgeof the sole..iAsaresultof this engagement, asjthe operator pulls the work towardhim, both armsbear yieldably againstthe opposite edges of the. flapunder the guidance of 1 "the edges of the sole-body. The flap is con'se-60;

table l2 into the space 18 beneath .the plate I4 70" V at the portion athereof. This is aslseenin'dashdot linesin Fig. 2. Contact with theplate .turns up the flap from the. sole-surfaces, and the ex tent ofmovement of .theworkin this direction .may be determined by theengagement of the. 7.5. l

. yielding asthe spring as elongates until the .en-- l tire width of thesole is inposition to receive contact of the rolls 34 amiss as theoperator draws '50 juncture of the flap and sole-body with the loweredgeof the plate. With the flap thus raised, the operator moves the solealong the table and plate tothe left toward the rolls 20 and 22, whichare in rotation. The curvature of theplate gradually bends the fiap awayfrom the sole-body through more than holding it clear of the roll 22.Between this roll and the lower roll 20, the heelportion of the sole nowpasses to receive a coating of cement over the surface s, but not at theextreme rear, where the area it extends beyond the inner end of the roll22 so that it is left uncoated. Continued advance of the work brings itbetween the pressure-rolls. 34 and 36, the mounting of which is such asto leave an uninterrupted space at their inner ends through which thework may be introduced. The flap is maintained at the rear of theserolls by its engagement with the inclined surface of the head 54 beforeit leaves the plate l4 and the rolls'20 and 22. As the workentersbetween the pressure-rolls, the positioning arm 60 is engaged bythe forward edge of the sole and is shifted as the operator enters saidsole longitudinally of the rolls to the desired extent. Depression ofthe treadle 46 causes the roll 36 to descend upon the sole in advance ofthe flap and effects the release of the positioning arm 62 by movementof the link 12. The elements directly co-operating with the work are asseen at the left of Fig. 2. The attachment is completed as the operatordraws the work out between the rolls 34 and 36, which press the flapupon the coated surface. In this movement, said flap is held inregistration with the sole-body by the engagement of'the arms 60 and 62at their edges. These arms are maintained by the sole itself in theproper relation to effect this and are free to adapt themselvestransversely of the sole to whatever position it may occupy. Thussecured to the solesurface s, the flap is protected against tearing ordistortion during succeeding operations, yet when it is tobe secured tothe heel-breast, it may easily be detached from the sole-body bygrasping it at the portion over the uncoated area u and drawing theremainder away from the sole.
